How do you get a random voice channel ID?-CodePudding

I am making a discord chatbot, but something I would like it to do is to join a random voice channel. I have tried the following from a different example, but you need to specify a channel ID. Which doesn’t suit my needs.

const channel = message.guild.channels.get('voiceChannelID');

I've also tried this from Check if a channel is a voice channel but it also requires a specific channel ID.

const channelObject = message.guild.channels.cache.get('channel id here'); // Gets the channel object
if (channelObject.type === 'voice') return; // Checks if the channel type is voice

It would be greatly appreciated if you could answer with some code that would find a random voice channel.

You can fetch all channels, filter them by their type and use Collection#random() to pick a random one from the returned collection:

let channels = await message.guild.channels.fetch();
let voiceChannels = channels.filter(ch => ch.type === 'GUILD_VOICE');
let randomVoiceChannel = voiceChannels.random();

Please note that in discord.js v13, VoiceChannel#type is GUILD_VOICE instead of voice. For more info see this answer.

I've had to grab all of the channels and filter out the voice channels before, so I just grabbed that code and flipped it around and added some random to it.

What I did:

    let channels = Array.from(message.guild.channels.cache.keys());

    const c = channels.filter(v => interaction.guild.channels.resolve(v).isVoice() == true);
    
    const index = Math.floor(Math.random() * c.length);
    
    const randomVoiceChannel = c[index];

The first line grabs all of the channels in the server.

The 2nd line removes the non-voice channels.

And finally the last 2 lines generate a random index from the array and outputs a value.

...

const randomVoiceChannel = Array.from(interaction.guild.channels.cache.keys()).filter(v => interaction.guild.channels.resolve(v).isVoice() == true)[Math.floor(Math.random() * Array.from(interaction.guild.channels.cache.keys()).filter(v => interaction.guild.channels.resolve(v).isVoice() == true).length)];

nifty 1-liner (please dont use this its incredibly unreadable i just thought it was funny)
